How to make a powerful mini freezer. Portable Mini AC up to -10ºC. In this video we are going to make an ultra-fast portable mini freezer that also serves as a portable air conditioner. It is capable of reaching a temperature of -10ºC in just 10 minutes.
This air conditioner works with a 9v battery and is perfect to carry in your car, for your caravan and to go camping now that the heat is coming. The heart of this cooling system is a small electric water pump that is typically used to circulate water in an aquarium.
